Schematic illustration of different inversions modes of a half graben, formed due to extension along a listric normal fault, containing pre-, syn- and post-rift sediments. a Half graben formation with roll-over anticline. b Complete reactivation of a normal fault, every normal fault segment is reactivated by reverse faulting, forming a harpoon/arrow-head anticline. c Shows a partial hanging wall by-pass, the lower part of the normal fault is locked and during shortening a new reverse fault geometry is formed, only the upper segment of the normal fault gets reactivated. d Complete hanging wall by-pass. In this basin inversion mode, the listric normal is not reactivated and the newly formed thrust ramps up into the post-rift sediments
